Subject: RE: rear view mirror
Ray Harroun=20
b. 1879 in Pennsylvaina. d. 1968.
Co-founder of Harroun Motor Co. in Fort Wayne, Michigan.
Race Car Driver - Winner of the first Indianapolis 500 in 1911.
His average speed was 74.59 mph (120.4kph), driving a Marmon.=20
He was the first to publicly use an automotive rear-view mirror=20
and so was rumored to be the inventor of the idea. However=20
Harroun readily acknowledged that he'd first spotted the rear-view=20
mirror years earlier on horse-drawn taxis in Chicago.
Interview with Dick Harroun, son of Ray:
Even over the phone, you can hear the pride in Dick Harroun's voice as =
he talks about his father's victory in the first Indy 500.=20
"He won the year before -- in 1910 -- but it didn't mean much =
because the track hadn't been paved with bricks yet. They ran on dirt.=20
"In those days, each car had two men in the cockpit -- a driver and =
a mechanic. The mechanic's main job was to look back and see who was =
coming up on them. My father wanted to go it alone, and they banned him =
from the race when he showed up on race day without a mechanic.=20
"It was 15 minutes before the start, and he went back into his =
garage and mounted a rearview mirror just over the dashboard."=20
It was a wide rectangular box with a mirror inside it. The officials =
saw what he had done and let him run.=20
"What really won the race for him, though, was that he went to the =
Firestone tire company and asked them how fast he could run without =
blowing any tires," Dick Harroun said. "He had noticed that the other =
cars were going into the pits all the time to have their tires changed. =
Firestone told him if he kept it under 75 mph, he'd be OK.=20
"He had to change only a couple of tires and a couple of them lasted =
all the way."=20
So, Ray Harroun created history in his Marmon Wasp by lasting more =
than six hours on the bumpy track and finishing nearly a lap ahead of =
his nearest competitor.=20
Ray Harroun never raced at Indy again but managed several teams. He =
hung around racing for the rest of his life, passing away in 1968.=20
"Obviously, I wasn't there when he won, but he spoke about it many =
times," Dick Harroun said. "He got credit for the rearview mirror, but =
what many people don't know is that he also was the man who developed =
bumpers on our cars."=20
He started laughing over the phone.=20
"That business of the mirror was something of a joke," he said. "My =
father said the mirror jiggled so much during the race that he could =
never use it. But I guess they thought it looked good, so they let him =
race."=20
So, even though this is a rediculously inappropriate question for =
info-performer, there are
still valuable lessons to learn from it:
1. Invention is often an incremental process (horse-drawn taxi mirror =
-> automobile mirror)
2. The leading edge/first instance/latest thing can be more about =
portent than utility (uselss jiggly mirror)
Michael "The early bird" Jones
P.S. The oldest US patent I found was #1365247, to Kennedy issued in Jan =
1921. Don't know about the
10 year interval batween Harroun and Kennedy.

Subject: Fire Animation
To all -
We're looking at giving an urban simulation demo
later this month at a Fire/Emergency conference.
We have a pretty good smoke animation that
we've created in MultiGen. It would be good to
include some fire/flames as well. Anyone have a good
flame/fire animation that they would be willing
to share?
- Bill

Hi, I'm using Performer on Linux and for the pefly program I'm trying to use my own GUI. For that I wrote GUI in LessTif and in main.C I've forked this GUI as a seperate process. The callback functions added to the buttons in the GUI, were able to access the shared variables, say ViewState->gui, for example.
Now the problem is, the callback functions were not able to update the shared variables. what might be the problem. ?. How do i make the callback back functions modify the shared variables. ?? Please help

If you're using SharedArenas with 2.3 or 2.3.1, then that's the problem. Performer 2.3 and 2.3.1 are single-process only and do not implement SharedArenas. If you're GUI must run in a separate process, then you'll have to create a shared memory area yourself with shmget(), shmat(), etc.

From: shankar++at++redwood.rt.cs.boeing.com (Shankar Swamy) Date: Fri, 8 Sep 2000 20:39:56 -0700 (PDT) Subject: inventor loader on Linux
Has anyone tried compiling this on Linux? The source in: /usr/share/Performer/src/lib/libpfdb/libpfiv/ compiles rather painlessly, but when I try to load a *.iv file, I get:
.... PF Warning: pfdFindConverterDSO() - Could not load DSO for extension "iv20" PF Warning: pfdFindConverterDSO() - Could not load DSO for extension "iv" PF Warning: pfdLoadFile() - Unable to load file /home/shankar/subdivision/newEq3.iv because of problem finding pfdLoadFile_iv
This looks like fix-able, but if someone has already figured it out, I would rather find my Friday evening doing something else :-(
Thanks.
Sincerely,
shankar

The following assumes you're compiling on Linux.....
I have a libpfiv.so pre-compiled with the open-source OpenInventor here:
If you're using TGS's Inventor, then try setting PFLD_LIBRARY_PATH to where your libpfiv.so is and set PFNFYLEVEL to 7....I suspect a symbol of some kind is unresolved and dlopen() is failing. Turning on those two environment variables will help identify which symbol is unresolved.
